all wizom it may concern: lie known list I, CARL Amman C01 subject of the King of Sweden, rein;' at Brockton, in the county of Plymh and State of Massachusetts, have inntcd certain new and useful Improvements in Engines, of which the following is ificetion. n s invention relates to engine operated b" the explosion of gas, combustible vapor, .c. its objectbeing the production or" such machine that is capable of great speed. Another object is the evolution of a derice ohereby one stroke of the piston will cause more than one complete revolution of With this and other objects in view the invention consists in the construction and combination of parts to be hereinafter fully described in the following s ecifications, oointed out in the claim and i lustrated in the drawings, in which- Figure 1 is a side elevation of the device showing the cylinder in section. Fig. 2 is a longitudinal cross section on line 2-2 of 1 showing the spring em loyed. Fig.

s a section on line 3-43 oi ll ig. 1. Fig. s a detail of the clutch employed.

Lilac reference characters indicate corren parts throughout the several ding}; views.

2? is the engine cylinder in which the pinton 33 operates, the exterior head of which is hollow and operates in a guide :irume 4 residing adjacent the open extremity of the engine cylinder and in alinemcnt there with.

is the engine shaft arranged in suitable hearings in the guide 4 and having a spiral groove 6 running around it.

i" is a sane secured in the hollow piston head (there are two shoes 7 arranged ditricnlly opposite each other) and adaptt vel in the groove (3 oi the shaft 5. is hollow throughout its length races :1 round shaft 8 to which it is shown in Near one of shaft 5 central longitudinal Specification of Letters Iatent.

a spiral s ring 10 one end of which is secured to tie in er shaft 8 and the opposite end to the guide 4: as shown in Fig. 2. An explosion in the cylinder forces the piston cutwardl causing the shoes 7 to travel forward in the roove 6 of shaft 5 thus rotating said shatt with the inner shaft rapidly to the right and tending to Wind the spring 10 upon said inner shaft. When the pis ton begins its return movement the shaft 5 is reversed and the spring 10 assists in the work of reversing this shaft, it thus also assists the piston in making the return stroke.

11 is a shaft independent of the mechanism so for described which is provided with a wheel 13 and clutch 12 on one extremity adjacent the guide 4 and which may convey power to a transmission shaft- K through the medium or bevel gears Y carried by the two shafts as shown.

11 is a disk keyed to inner shaft 8 and capable of enga ement with clutch 12 when revolved to the right but free from the same when revolved in the opposite direction. This arrangement enables the piston to transmit power to shaft 11 on every outward stroke.

With my arrangement the number of rerolutions imparted to the shaft bv an explosion depends upon the form at that usploeiou coupled with tho ivngrtb of the groove in said shaft and it matters not at what position on the shaft the outer cylinder head may have at the time oi an e3;- plosion, ower is conveyed to shaft 11.

.'What claim is:

The combination of, a member 2, a reciprocating member having its exterior head hollow working in said member 2 a shoe carried in said hollow head, a guide l in alincment with the aforesaid member 2 adapted to surround and embrace the hollow head, a hollow spirally grooved shaft having; its cavity enlarged at one extremity runniiv longitudinally of said guide and sdapte to engage said shoe, an inner shaft keyed to said hollow shaft, a disk keyed to said inner shaft, a clutch 12 engaged thereby ill and a spiral spring Within the before-men I t-ure in the presenceof two subscribing wittionecl enlarged cavity of the hollow shaft nesses. havilf one extremity secured to the inner sheft :Yhile the opposite is secured to the CARL ALFRED S gulde. l Witnesses:

In testimony that I claim the foregoing CARL MAGNUs PETERSON, as my own I have hereto affixed my s1gna- V KLAS ALFRED ROHMAN.
